What it is

Hyvor Blogs is an open-source, self-hosted blogging platform maintained by HYVOR and written primarily in PHP under the AGPL-3.0 license. It is built for speed and simplicity while remaining flexible enough to support anything from a straightforward personal blog to more complex publishing workflows. The project ships as a full application rather than a library: a console and editor frontend built with SvelteKit and the Hyvor Design System, an API backend built on PHP and Symfony, and PostgreSQL serving both as the database and as the queue backend. It lives in the PHP and Symfony ecosystem, with a SvelteKit frontend, and sits in the self-hosted CMS and blogging category alongside the topics blogging, blogging-platform, and cms.

The concrete problem it solves is ownership and consolidation of a publishing stack. Rather than combining a hosted blog service, a separate SEO plugin, a comments or membership add-on, and an authentication provider, operators get one installation that handles multiple blogs, custom domains per blog, built-in sitemaps and Open Graph metadata, Atom feeds, role-based users, and redirects in a single deployment. Authentication is delegated to any OIDC provider such as Authentik or Keycloak, so an existing identity system can be reused instead of introducing another credential store. Content can be imported from WordPress or a sitemap and exported at any time, which limits lock-in, and an AGPL-licensed codebase means the platform can be inspected, modified, and extended directly.

Key capabilities

• Self-hosted deployment driven by Docker Compose, with self-hosting instructions published in the project documentation.
• Multi-blog hosting from a single installation, including custom domains per blog and customizable URL routes with managed redirects.
• Block-based rich text editor supporting images, videos, code blocks, and Markdown, with a suggestion mode for proposed changes.
• Theme system with a template language plus CSS and JavaScript for full customization of each blog.
• Built-in SEO output covering sitemaps, Open Graph tags, and canonical URLs, alongside automatically generated Atom feeds.
• OIDC single sign-on with providers such as Authentik and Keycloak, plus per-blog role-based access control for authors and editors.
• Console API for automations, Data API for headless usage, Delivery API for sub-directory hosting, and HTTP webhooks for post, tag, and member events.
• AI agent that reviews posts and suggests improvements, and internationalization supported from the ground up without plugins.

Who uses it and how

• Individuals and small teams hosting one or more personal or project blogs on their own infrastructure behind a Docker Compose stack.
• Organizations with an existing OIDC identity provider that want blog authentication to flow through the same single sign-on system they already operate.
• Development teams running Hyvor Blogs headlessly, consuming content through the Data API while serving a separately built frontend.
• Publishers hosting blogs in a sub-directory of a larger site, using the Delivery API for that arrangement.
• Migrators leaving WordPress or another platform,
